ipad 4: I just installed IOS 17.7.10. Now that I installed 17.7.10, I can't get on the internet. I can get on Facebook, etc, but for the internet, the dialog box says there is no internet available. I use my ipad on wifi only.
iPad, iPadOS 17
Assigning a static IP Address may or may not alleviate the problem. Given that a router restart was required, this might suggest the issue was with the Router's ARP table.
Without delving too deeply into the intricacies of how IP networking actually works, ARP tables are used to "convert" a device's IP address (however it is assigned) to the devices current MAC (i.e. physical) address. Your iPad (or any other device) will use one or more MAC addresses to operate on the local network - and for privacy may use a randomly generated MAC Address in preference to the device's unique "burned-in" address. When using the iPad's Private Address feature, the MAC address can periodically change.
The Router may lose track of a device's MAC address when it changes - a restart of the router resetting the ARP table and restoring normal address resolution.
After restarting your Router, assuming that the Router is acting as your local DHCP server, you may need to either restart other devices that share the same network - or perform an IP Address refresh on the other devices - as otherwise you may encounter duplicate IP Addresses on your local network. Using static IP Addresses can avoid this problem, however, you must be careful to ensure that static IP addresses that you assign are unique on your network.
WiFi/Internet connection difficulties are usually an indication that your device does not have a routable IP Address - your IP Address usually being assigned by DHCP. When problems occur, your iPad may only have a self-assigned link-local IP address that begins 169.254.x.x.
You can verify your DHCP-assigned IP Address from settings:
Settings > WiFi > [Your WiFi Network / SSID] - tap the blue “i” icon - [IPv4 Address] IP Address
If you have a VPN App or profiles installed, or a security/AV/firewall App such as Norton, these may be interfering with DHCP and preventing your device from obtaining a valid IP Address for the WiFi network to which you are attempting to connect. The resolution is usually simple; if installed, you may only need to temporarily disable or remove the Security App and/or VPN.
DHCP is frequently used to automatically obtain an IP Address. Until your iPad has a valid IP Address to connect to your network, you will not have an internet connection. Disabling or removing VPN and/or the offending security App should allow DHCP to operate normally - allowing connection to your network and the internet.
If this resolves your issue, the VPN and/or security App can be reinstated after the connectivity problem has been resolved.
If some Apps are working as expected, while others are not - or other devices can connect to your WiFi network - you may find that a restart of your WiFi Router, followed by a restart of your iPad will clear the problem….
To restart your router, disconnect power from the router for at least 30 seconds - then reconnect power to restart. After your router reboots (which may take several minutes), force restart your iPad:
Force restart iPad (models with Face ID or with Touch ID in the top button)
If your iPad doesn’t have the Home button, do the following:
Force restart iPad (models with the Home button)
Press and hold the top button and the Home button at the same time. When the Apple logo appears, release both buttons.
If you continue to have difficulties, check to see if your iPad is using the WiFi Private Address feature. This feature is intended to provide additional privacy and security when using “public” (untrusted) WiFi networks.
Settings > WiFi > [Your WiFi Network / SSID] - tap the “i” icon - Private Address
The Private Address feature is largely unnecessary for your home WiFi network; if enabled, Private Addressing can cause issues if specific MAC addresses are expected by your WiFi Router. You may need to disable this feature - and can be enabled or disabled for each individual network.

Thank you! I did as you suggested, and it worked. The big key was restarting the modem. Do you think it would be a good idea to make the iPad have a static IP? I have done that with most of my other devices on my network and that seemed to solve the problem of having duplicate IP addresses that I've had in the past (when I didn't have static IP addresses).
Just installed IOS 17.7.10 on ipad 4. Now I can't get on the internet
